UNITED STATES I j PATENT OFFICEo REUBEN VOSBURGH, OF OREGON, ILLINOIS, ASSIGNOR OF ONE-HALF TO SANFORD D. WALLACE, OF SAME PLACE.

SASH-WEIGHT.

SPECIFICATION forming part of Letters Patent No. 326,073, dated September 8, 1885.

Application nien November 29, 1ss4. (No model.)

.weight, the construction of the several sections is such as to prevent the axial or rotary movement of one section upon another, and at the same time prevent the lateral displacement of one section upon another; and the object of my present improvement is to effect the same purpose by a novel construction designed with special reference to effectiveness and absolute certainty in obtaining these objects; and also to prevent the catching of one weight upon another when two lines of weights are used in the same box, by means of a construction in which there will be no edge orsurface at either end of each section at rightangles to the outer walls of the section. Each section of the weight has a conical formation at its upper end scalloped at two or more points on its ini clined surface, so as to leave radial ridges, the scallops and the ridges extending from the outer wall to the ropelchannel, so that this scalloped surface at every point along the outer wall will be inclined to the rope-cham nel, and thus offer no ledge at the joint of the sections upon which another weight could catch and be held in the passing movements of the weights. The lower end of each weightsection is correspondingly scalloped in cup shape, and the inclined walls of the scallops form a serpentine edge, joining a serpentine wall-line below the'apex of the cone when the weight-sections are strung upon the rope, making a serpentine joining of conical surfaces, which hold the sections from any separate movement one upon the other, and avoid a ledge-surface at the wall of the joining.

Referring to the accompanying drawings,

Figure l represents in elevation my improve-d sectional weight; Fig. 2, an elevation of one of the weight-sections, and Fig. 3` a central section of one of the weight-sections.

A suitable number of sections, a, compose the weight, and they are strung upon a rope, b, in the usual manner. Each section has a central ropechannel, c, which tapers from its base to the top, and is preferably a poundweight. The top of each section is made conical, and is formed with two or more surfacescallops, d, preferably four, of equal area, so that the inclined sides of the conical end have also a curved formation and `a formation of ridges, e, separating the scallops. The base of each section has the form of an inverted cup with a scalloped edge formation, f, the scallops extending to the central opening, and the counterpart of the top end scallops,so that the each other in their ascending and descending movements in the box or window-casing.

It is important also to notice that the tapering form of the rope-channel c, with the matching cone and cup formation d e f 9,'

places the small end of the channel of one section up in the large end of the channel in the sections will fit together with matching scalupper section, as in Fig. 3, and thereby prevents the cutting of the rope at the joining of the sections, because the channel of one section practically telescopes with the channel of the other section in a weight of sections made practically a single weight, because each section is so braced in the line as to practically lock the sections togetheron the rope.

I claim as my invention A sectional Weight having its top formed with pointed or conical-shaped scallops ,d and ridges e, extending from the outer wall to the :i ledge at thejoining, for the purpose Set forth. rope-Channel, forming a serpentine wall-line In testimony whereof I aix my signature below the apex, its lower end oupshaped,hzw in presence of two witnesses. ing inclined scallops extending from and form- REUBEN ing a serpentine edge at its Wall, whereby the l sections will join at the wall upon surfaces in- @lined to the vertical line of the wall to avoid u VOSBURGH.
